JU(1) JU JU(1)
NAME
ju - show node availability and usage
SYNOPSIS
ju [-slinczh]
DESCRIPTION
ju reports, for each configured partition, the total number of nodes,
the number of nodes down, the nodes used, the nodes currently avail-
able, and the percentage of nodes up that are being used. It also shows
a brief listing of users currently running jobs and the number of nodes
used by each job.
COMMAND-LINE OPTIONS
-s Include the partition status in ju output. The partition status
is either "up" or "down."
-A Replace username in ju output with the account name for each
job.
-l Include a short job status string for each job in the listing of
running jobs. The status string is appended in parentheses, and
may be "run" for a running job, or "cng" for a completing job
(those jobs that are currently being removed from the system are
considered "completing").
-i Include the job id for each job in the listing of running jobs.
The jobid is appended to the job information in parentheses.
-n Include a count of running jobs before job listing.
-c Report number of CPUs instead of number of nodes.
-z Attempt to compress job listing by only showing identical job
strings once. (E.g. "user1-1, ..., user1-1" ==> 2*[user-1], ..
-h Show a short usage message.

ju shows the following without any options:
